About User Manual and TruFlow Lite System This manual will cover basic operation as well as advanced setup of your TruFlow Lite system. Main windows, which include the Dashboard, Power, Operation Status, and Primary Toolbox windows, will be underlined and bolded. Icons to be touched to take you to another window will be bolded. Auxiliary windows, like the Automatic Start/Stop Schedule setting windows, will be underlined.

Typical TruFlow Setup:

TruFlow Lite measures heat from the appliances and automatically adjusts fan speeds throughout the day, giving you the precise amount of exhaust at all times. As more cooking appliances are used the exhaust and supply volume increase; as fewer appliances are used, the exhaust and supply volume decrease. You have the ability to increase the exhaust volume to 100% at any time. Because you control it, overrides are kept to a minimum to maximize energy efficiency. The override system runs for an adjustable timed period of 15 minutes and can be activated on the panel or via as optional remote control. TruFlow Lite monitors ventilation system efficiency relative to your utility costs, in real-time, so that you can manage your kitchen to take advantage of off peak times by turning down appliances. Setting an energy reduction goal reduces your utility costs even more!

Main System Components

This is your TruFlow Lite Touchscreen panel. The panel can be mounted on a wall or on of the hoods and puts operation of your kitchen exhaust equipment at your fingertips. Additionally, the TruFlow can be set up to control up to seven cooking appliances, seven external lighting zones, and two extra exhaust hoods connected to motor starters.

Variable Frequency Drive (VFD) Each exhaust fan has its own variable frequency drive. The TruFlow sends a signal to the drive telling it to slow down or speed up the fan. Some makeup air units will also have a VFD.

J-Couple TruFlow measures the temperature in each exhaust duct collar for each hood connected to an exhaust fan that will be sped up or slowed down using a j-couple.

When the kitchen staff is meeting or exceeding the Energy Reduction Goal, the bar will be green.

If the kitchen staff is not meeting the Energy Reduction Goal, the bar will be red. The Energy Reduction Goal is initially factory set to 20%, however this number can be adjusted as needed to encourage staff to be more energy efficient.
